  38 # Parse the NASM version file and produce appropriate macros
  39 #
  40 # The NASM version number is assumed to consist of:
  41 #
  42 # <major>.<minor>[.<subminor>][pl<patchlevel>]]<tail>
  43 #
  44 # ... where <tail> is not necessarily numeric, but if it is of the form
  45 # -<digits> it is assumed to be a snapshot release.
  46 #
  47 # This defines the following macros:
  48 #
  49 # version.h:
  50 # NASM_MAJOR_VER
  51 # NASM_MINOR_VER
  52 # NASM_SUBMINOR_VER     -- this is zero if no subminor
  53 # NASM_PATCHLEVEL_VER   -- this is zero is no patchlevel
  54 # NASM_SNAPSHOT         -- if snapshot
  55 # NASM_VERSION_ID       -- version number encoded
  56 # NASM_VER              -- whole version number as a string
  57 #
  58 # version.mac:
  59 # __NASM_MAJOR__
  60 # __NASM_MINOR__
  61 # __NASM_SUBMINOR__
  62 # __NASM_PATCHLEVEL__
  63 # __NASM_SNAPSHOT__
